An imprinter apparatus which utilizes a print roller traveling within a carraige over a base plate is provided with a rolling assembly which engages channels in the base plate to minimize play between the carriage and the base plate. The rolling assembly includes a first set of rollers which are laterally constrained within the carriage, a second set of rollers which are free to move laterally, and means for retaining the rollers in the channels. The imprinter apparatus is further provided with ...

A bidirectional imprinter having a print roll carriage with sidewalls and two pairs of inclined slots disposed in the sidewalls where the first pair is oppositely inclined with respect to the second pair. First and second print rolls are respectively associated with the first and second pairs of slots so that movement of the carriage over the print bed causes the first print roll to move down its associated slot pair to effect imprinting while the second print roll is moved up its associated slo...

An imprinter comprising a unitary, extruded base with an elongated receptacle extending along the upper length thereof and a molded plastic print bed inserted within the receptacle. An elongated recess in the print bed may also be provided so that a portion of a credit card or the like overlying the recess can be depressed therein to raise the remainder of the card and permit easy removal thereof.

Electric motor driven imprinter apparatus for imprinting characters from a character imprint source member onto document sheets or the like, including a housing having a driven roller moved back and forth transversely across an imprint station, a horizontally slidable carrier block member and a changeable cassette carried by the block member having a changeable vertically slidable roller block member and a roller rotatably carried thereby. A pair of spaced apart rotatable sprockets and an endles...

An imprinter with a lifting system for lowering the platen roller during the imprint stroke and raising the platen roller during the return stroke. The lifting system includes a lift cam lever and lifting cam associated with the front wheel and kept under constant bias. The lifting cam lever engages in slots arranged along a track of the imprinter bed, and the front axle is eccentrically mounted in the lifting cam such that when a carriage assembly having a platen roller is moved through the imp...

A portable imprinter for transferring data, in the form of raised characters on a credit card or the like, to a receiving paper by pressure. A pressure element is mounted directly in an actuator which slides in grooves formed in the wall of a frame member, and travels across an opening into which it protrudes slightly to press the receiving paper with its transfer element against the card.

A data recorder in which a printing member credit card is mechanically driven through operative stages, a variable numbering head is set by electronic control, and a form holder is automated to place a print-out form in print position by program control.

A manual printer has a set of type wheels turned and set by manually operated rack bars which have additional slanted recesses and projections engaged by a spring-biassed arresting bar which is resiliently and yieldingly displaced by the slanted portions during setting of the type wheels. The blocking lever is biassed by a strong spring to block the yielding movement of the arresting bar, but is held in an inoperative position by a feeler lever engaging a wheel of the platen carriage when the ca...

A portable imprinter for transferring indicia from a printing plate to a document comprising a generally rectangular base adapted to support the document in printing disposition over the plate, a frame mounted on the base, a pair of longitudinally extended slots located on opposite sides of the base at its junction with the frame for insertion of the printing plate and the document, and an imprinting roller assembly comprising a generally rectangular reciprocable carriage movably mounted within ...

A credit card imprinter with a base for retaining the printing elements and transaction form. The imprinter includes a platen adapted to be moved from an initial position to an extreme position and back over the printing area on the base. Gear wheels are provided for positioning print wheels, and a stop means is provided to prevent movement of the platen to a movable mode until all the print wheels have been reset by actuation of a reset handle preceding a printing operation.
